The cyclic hydropower system includes a power generation device. The first power generation device includes a circular frame pivoted on an axle whose one end is coupled to an end of the axle. A number of basins are arranged around the circular frame. An arc trough is positioned at a distance from and along an arc section of the circular frame. A channel is formed between the arc trough and the circular frame allowing the basins to move through. The channel has inlet at an upper position and an outlet at a lower position. A tank is positioned beneath the outlet of the power generation device, a pumping element is provided inside the tank, and a pipe extended from the pumping element above the power generation device with a pipe outlet above the inlet of the power generation device.

The hydraulic generator includes a first structure; a second structure, such that a water passageway from the inflow port to the outflow port is formed by the first structure and the second structure in a state that the second structure is attached to the first structure; a water turbine; and an electrical generator. The second structure is removable from the first structure, and includes a fixing portion fixing the fixed shaft.
